Description

[Detailed explanation of the invention] "Industrial application field" This invention is a drain shelf installed in the kitchen.
This invention relates to a sliding fixing device for a sliding shelf installed vertically slidably between left and right legs.

"Prior Art" The applicant had previously devised a drain shelf introduced in Japanese Utility Model Application Publication No. 117326/1983 as a drain shelf similar to the product of the present invention.
A sliding groove is provided along the center line of the front and rear legs that make up the left and right legs, and a tightening screw inserted from the outside into this sliding groove is inserted into the shelf side frame to tighten and secure the shelf to the legs. The height of the shelf can be adjusted by loosening the tightening screw and sliding it up and down along the sliding groove along with the shelf.

``Problem to be solved by the invention'' By the way, in the conventional example, in order to form a sliding groove along the center line of the front and rear legs, it is necessary to form two legs as shown in the example diagram described in the same publication. However, it is unreasonable that the leg body requires a complicated process and high-quality wire material, and the processing time and cost are high.

Therefore, in the present invention, in order to eliminate the above-mentioned unreasonableness, we have created a drain shelf that can be provided at low cost by eliminating the labor involved in constructing the legs, saving material costs, and reducing costs. The technical problem is to provide a reliable and simple means for sliding and fixing the body.

``Means to solve the problem'' As a means to solve the problem, an inverted U is placed on a horizontal base.
By planting a curved rod in the shape of a letter, the front and rear leg rods are placed opposite each other on the base, and these legs are placed opposite to the left and right, facing the front and back of the outer surface of the side frame of the draining shelf installed between the two legs. A fixing band is provided at the front and rear of the band plate, with a pair of engaging grooves facing each other facing each other, and a concave curved surface shaped to fit outwardly on the outer surface of the front and rear leg rods. The shelf board is secured by fitting the fixing band to the outside of both leg rods by engaging it in both engagement grooves of the frame, and inserting the tightening screw between the front and rear leg sticks from the outside of the fixing band toward the shelf side frame. The drain shelf is equipped with a sliding fixing device that is fixed to the legs.

"Operation" Both ends of the fixing band are engaged with both engaging grooves of the shelf side frame, and the concave curved surface of the fixing band is fitted to the outside of both the front and rear leg rods, and the shelf side frame is inserted from the outside of the fixing band between the front and rear leg rods. When the tightening screw is inserted toward Since the concave curved surface presses the outer surfaces of both the front and rear leg rods as the center of the fixing band is tightened, the leg rods are pressed against the outer surface of the shelf side frame, and as a result, each member is joined at the tightening part. Due to the frictional resistance of the surfaces, the shelf side frame is firmly fixed to the inner side of the leg, thus fixing the shelf.

Further, when the tightening screw is loosened, the pressure contact portion is relaxed and the pressure contact is released, so that the shelf side frame becomes vertically slidable relative to the leg body, and the height of the shelf can be adjusted.

"Example" Embodiments of the present invention will be described with reference to the accompanying drawings.

Fig. 1 shows a perspective view of the entire structure of a draining rack according to an embodiment of the present invention. By planting the curved rods 3 in the shape of a letter, both the front and rear leg rods 3
a and 3b are configured. Incidentally, round contactors 4, 4 to be placed on the floor are inserted into the front and rear parts of the bottom of the base 2.

This leg body 1 has two lattice-shaped draining shelves 5, 5 constructed in two stages above and below the space between the legs, which are arranged oppositely on both the left and right sides, and the shelf board 5 has a surrounding frame with a band plate. The formed front and rear frames 5a, 5b and left and right side frames 5c, 5d are framed in a rectangular shape, and each joint is welded and connected to form a rectangular peripheral frame. 5e and three vertical wires 5f are orthogonally connected to form a lattice surface, which is fitted and fixed, as shown in an exploded view of one side of the shelf. After bending each end of the front frame 5a and the rear frame 5b to provide a bending step portion 5g that bulges outward, the inner portion of the bending step portion is further bent at a right angle. Then, arrange the front and rear frames with the respective bent right-angled portions facing each other, fit the both side frames 5c and 5d along the inside of the frames, and fit both ends of the side frames to the inner surfaces of the right-angled bent portions of the front and rear frames. By welding, opposing engaging grooves 6, 6 are formed on the front and rear sides of the outside of the side frame.
It constitutes a peripheral frame body in which is formed.

Reference numeral 7 is a fixing band for the shelf board, and concave curved surfaces 7a, 7a shaped to fit on the outer surfaces of the front and rear leg rods 3a, 3b of the leg body 1 are provided oppositely at the front and rear of the band board, and both front and rear ends 7 of the shelf board are fixed.
b, 7b protrude to both sides, and a small hole 7 is formed in the center part 7c.
d, 7d, and as shown in FIG. 3, both front and rear ends 7b, 7b of this fixing band 7 are engaged with both opposing engagement grooves 6, 6 on the front and rear outer surfaces of the side frame, and a double concave curved surface 7a. , 7a are fitted to the outside of both the front and rear leg rods 3a, 3b, and the legs and the side frame are fitted together,
By screwing the tightening screws 8, 8 inserted from the outside of the central part 7c into the screw holes A and B of the side frame through the small holes 7d, 7d, the combined member is tightened, and the shelf board 5 is fixed to the leg 1.
It is fixed at

FIG. 4 shows another embodiment of the shelf board tightening means, and in this embodiment, the front and rear of the side frame 5c' also correspond to the front and rear concave curved surfaces 7a' and 7a' of the fixing band 7'. The concave curved surfaces C and D are formed symmetrically, and both the leg rods 3a and 3b are clamped and compressed by these concave curved surfaces on both the inside and outside, so that they are crimped and fixed.
It is expected that the shelf board will have a stronger fixing effect than the previous embodiment.

``Effect of the invention'' At both sides of the shelf board, the leg rods are held between the outer sides of both the front and rear leg rods, the fixing band is fitted, and both the front and rear ends of the fixing band are engaged with the engaging grooves on the outer surface of the side frame. By fitting the front and rear concave curved surfaces of the fixing band to the outer surfaces of the front and rear leg rods, and then screwing the center part of the fixing band into the shelf side frame with a tightening screw, the shelf side frames are attached to both the legs. It is fixed in a crimped state, and the shelf plate is securely fixed between the left and right legs, maintaining a horizontal position, and being able to withstand the load of the articles placed on the shelf.

In addition, by loosening the tightening screws of the fixing band, the shelf board can be slid up and down along the legs, so the height of the shelf can be easily adjusted, and the height of the shelf can be adjusted according to the convenience of use. The height can be changed arbitrarily.
